Answer:
The drugs that do not act on receptor site are:
Purines, Antacids
, Osmotic diuretics
.
Explanation:
To say a drug acts by mechanism means that it that the drug is engineered to produce a specific effect on the body by acting on enzymes or receptors.
Receptors are molecules made up of protein and can be found in target cells.
There are a few drugs that do not interact with enzymes or receptors to create the expected results on the body. Examples of the same are given above.
- Antacids are a category of drugs that act to reduce or remove acidity in the stomach
- Osmotic diuretics are designed to increase blood concentration and renal filtrate.

Answer:
b
Explanation:
In this question, the context for exponential growth is assumed to occur naturally. Because lab experiments are not natural and must happen in well controlled studies, it cannot limit exponential growth.
Answer:
The correct answer will be-
1. Mobile elemests- LINEs and SINEs
2. Exons
3. Non-coding RNA genes
4. Introns
5. Repetitive DNA sequence
Explanation:
The human genome represents the total nucleic acids present in the Homo sapiens packaged in 23 chromosome pairs and contains 3 billion DNA base pairs.
The human genome comprises of protein-coding genes and non-protein-coding genes. The protein-coding sequence accounts for only a very small proportion that is 1.5% whereas the rest non-coding sequence accounts for 98.5%.
The non-coding sequence includes the Non-coding RNA genes( microRNA, small nuclear RNA), Introns which accounts for 26%, Repetitive DAN sequence (50%), mobile elements like LINEs and SINEs and exons.
Thus, Mobile elements- LINEs and SINEs, Exons, Non-coding RNA genes, Introns and Repetitive DNA sequence are the correct answers.
That's our thoughts I hope this helps
